Installation

TPE E-circulators

Other connections TPE

See the wiring diagrams for instructions how to con-

nect external potential-free contacts for start/stop and

digital function, external setpoint signal and fault sig-

nal.

Connect the wires to the following terminal groups:

Note:

• As a precaution, separate the wires from each other

by reinforced insulation in their entire lengths.

• If no external on/off switch is connected, maintain

the connection across terminals 2 and 3.

Group 1: Inputs (external start/stop, digital function,

setpoint and sensor signals, terminals 1-9

and bus connection, A, Y, B).

All inputs are separated from the mains

conducting parts by reinforced insulation.

Group 2: Output (signal relay).

The output, terminals C, NO and NC, are

galvanically separated from other circuits.

Therefore, the supply voltage or protective

extra-low voltage can be connected to the

output as desired.

Group 3: Mains supply.
